A teenfag is someone usually between the age 13 and 19 who acts in a stereotypical teenage way. The term "teenfag" covers a vast array of people, as the
definition is very broad.
There are two categories of teenfag: typical and atypical.
Typical refers to the annoying ones who listen to generic modern pop music and/or mainstream hip-hop, dress
like sluts/douchebags, and use annoying catchphrases borrowed from ghetto speak
like "fleek" or "
bae" (and formerly yolo and swag). They tend to be obsessed with social media and are never seen without their smartphone that their parents paid for. You will typically see them hanging out in groups of various sizes.
Atypical refers to the "edgy" teenfags that dress
like complete buffoons and are always carrying some kind of label
like emo, goth,
scene, or whatever other shitty pseudoculture they could dig up. They tend to listen to very specific genres of music, all of which tend to be equivalent to ear rape. Their goal in life is to "stand out" by conforming to a preexisting group, making them even bigger tools than typical teenfags. They too, tend to always be carrying a smartphone, but they behave
like rats on social media (by showing off cutting themselves, talking about how they hate everyone, etc.).
Either way, all teenfags are
cancer.
